  1. Global Climate Observing System Ozone Research Managers’ Meeting David Goodrich Director, GCOS Secretariat World Meteorological Organization

  2. Outline • GCOS Overview • GCOS and GAW Ozone Networks • Report to UNFCCC and Second Edition Implementation Plan • GCOS Reference Upper Air Network: Progress to Date

  3. Global Climate Observing System • Mission: To ensure that the data required to meet the needs of users for climate information are obtained and made available for: • Climate system monitoring, climate change detection and attribution; • Research, modelling and prediction of the climate system; • Assessing impacts, vulnerability & adaptation; • Application to sustainable economic development. Global, long-term, high-quality, sustainable, reliable, …

  4. GCOS is comprised of climate components of various global observing systems including both satellite and in situ observations Global Climate Observing System (GCOS) WCRP/GEWEXBSRN Other WMO WWW Global Observing System (GOS) Atmosphere WMO World Hydrological Cycle Observing System (WHYCOS) Land/Water WMO Global Atmospheric Watch (GAW) Atmospheric Chemistry FAO Global Terrestrial Observing System (GTOS) Land IOC/ UNESCO Global Ocean Observing System(GOOS) Ocean

  5. Recent GCOS Actions on GAW Ozone Networks • GCOS Steering Committee (October 2007) recognized: • GCOS Global Baseline Total Ozone Monitoring Network • GCOS Global Baseline Ozone Profile Network • Atmospheric Observation Panel for Climate (AOPC, April 2007): • Recognized high data reception rates for GAW ozone networks • Recommended one-stop point for submission and access to data

  6. GCOS Implementation Plan (2004) • Responds to UNFCCC request to develop an implementation plan that considers: • Requirements in the ‘Second Adequacy Report’; • Essential Climate Variables (ECVs) • Integrated global analysis products • Views of Parties with respect to that report; • Existing global, regional and national plans; • Open review by broad range of scientists and data users; • Indicators for measuring implementation; • Implementation priorities and resource requirements. • Identified as the Climate component of the Global Earth Observing System of Systems (GEOSS)

  7. Ensuring the Satellite Climate Record • Scientific Requirement Definition • Preparation of GCOS “Satellite Supplement” (2006) • Ongoing Scientific Interaction • Satellite Agency Coordination • Committee on Earth Observation Satellites • Formal CEOS response to UNFCCC • Coordination Group for Meteorological Satellites • Objective: Stable, Calibrated Satellite-based Climate Products • An interruption in a national satellite contribution should not mean a failure in the Climate Record

  8. UN Framework Convention on Climate Change GCOS-Related Actions - 2007 • Adopted the revised UNFCCC reporting guidelines on global climate observing systems • Invited Parties to submit to GCOS Secretariat “additional information” on observing systems by 15 Sept. 2008, using these guidelines • Requested CEOS report on satellite observations for climate in December 2009 • Urged Parties implement GCOS Regional Action Plans • Requested comprehensive report on GCOS implementation in June 2009 (restated)

  9. Reconsidering the Observing System: Toward a GCOS “Comprehensive Report” GCOS Performance Monitoring Data Done GCOS “Comprehensive Report” (2009) Reporting Guidelines(2007) “National Activities” Information (2008) Done Steering Committee, Science Panels, Partner OS Inputs Lessons from IPCC (2007)

  10. GCOS Reference Upper Air NetworkRationale • Motivation • Problems for climate in accuracy, long-term stability • Changes in measurement systems • Objectives • Provide long-term, high-quality climate records • Constrain/calibrate data from more spatially-comprehensive global observing systems (including satellites) • Measure large suite of co-related climate variables

  11. Climate driven Spatial density Benchmark Network ~10 stations Upper Air Reference Network 30-40 stations GCOS Upper Air Network (GUAN) 163 stations Comprehensive observing network All stations, observing systems, reanalyses etc. Proposed Observing System Architecture

  12. GRUAN Progress to Date • Climate Requirements Established: Boulder Workshop 2005 • Instrumentation/Siting Options Assessed: Seattle Workshop 2006 • Report on Requirements, Siting, Instrumentation: July 2007 • Lindenberg designated as Lead Centre; Director Holger Voemel • Initiation Meeting at Lindenberg 25-28 February: “Start small, but start” • Community Presentations • WMO CIMO, CBS groups • WCRP Observations and Analysis Panel • GCOS Atmospheric Observation Panel for Climate • AMS • Ozone Research Managers • Lindenberg Report to be released; Invitations to stations

  13. Proposed Site Instrumentation Level 1 (Highest Priority) Measurements • Standard surface variables (pressure, temperature, humidity and wind) • Redundant / simultaneous measurement of temperature and water vapor • Pressure and GPS / radar height • Ground-based GPS receivers (column water vapor) Level 2 Measurements • Surface radiation (BSRN suite) • Microwave radiometer (temperature/moisture profile) • Multi-channel infrared radiometer (such as AERI; temperature and humidity properties and cloud retrieval) • Integrated trace gas (at least ozone) measurements • Column aerosol measurements from sunphotometers

  14. Proposed Initial GRUAN Sites • Darwin, Australia • Xilin Hot, China • Sodankyla, Finland • Lindenberg, Germany • Potenza, Italy • Cabauw, Netherlands • Lauder, New Zealand • Payerne, Switzerland • Barrow, USA • Beltsville, USA • Boulder, USA • Lamont, USA Italics: GAW Ozone Profiling Stations
